Be it known that I, .l'lnnnsr Knmrrz, a citizen of the United States ofAmerica, and residing in' the horou h of Brooklyn, in the city of NewYork, county of Kings, and. State of New York, have invented certain lm:provements in the Constructio'n of Pallet Boards, of which the followingis a specification My invention relates to improvements in theconstruction. otpanelboards an d the like.

The main object of this invention is to produce a panelboard cornerpiece so constructed that the sides of varying thicknesses and withunfinished edges may be ill. ily secu ed to each other and. to the basewithout h g to drill or to bore holes in the slate or other material,and at the same time produce a simple and inexpensive device so that anyone with ordinary skill and intelligence may put the parts together toform a panel-board combining strength with neatness andlinishedappearanc'e.

In the accompanyingdrawings Figure 1 represents a sectional plan View ofone corner of a 'panelhoard embodying my invention; Fig. 2 represents anelevation of the body of the corner piece detached; Fig. 3 represents anelevation of the finishing piece; Fig. e is an inverted plan view of thefinishing; piece shown in 3 taken on the line e e; and Fig. 5 representsa sectional. modification on a smaller scale.

I Referring to these drawings A, 31, represent partsof the two sides ofthe panelhoard ii.

B represents the body part of the cornerpiece, which in cross section,is substantially right angular, the sides 1), b, of the right angle Thispiece may be stamped from iron or any other suitable material.

In the sides 5, b, are lugs 6 t, which are punched inwardly from thesides into planes parallel with the flanged edges 6, adjoining the sidesfrom which they are punched, or in other words, plan erpen.di 1 ulnr tothose sides. As shown in the drawing these I are punched alternatelyfrom the oppo sides, I), Z

011 the edges 6 lugs t m jecting at aslight angle, holes are tapped toreceive bear at a slight angle a These "screws may be tights sides areput in place to secure an of slate. This piece B is l'qncss ed to the ofthe panclhonrd A in anysuilablc manner. Preferably a plate lrl is tllied to, or made integral with, tlw'cpieceiB o.nccnd at right anglesthereto, and Qthroup'h llris plate belts or screws Z) ma pass} to h oldthe corner piece in upright positionlfi The lining or finishing piece (1ol the corner consists of a piece of sheet copper, or other suitablematerial, having inwardly bent flanges that are adapted to slip over andinclose the lugs At one endoi-tliis piece a plate C, which is adapted tocov er the top of the corner and conceal the join when put in place. 4

in assembling the parts,

the piece then inserted in the space betweenithe :oiuer edges and thelugs D The corner liixiiin C is inserted to inclose the lugs and wedgethe slates in place, after which the screws may be tightened ifnecessary. The plate C covers the top ofthe joint or corner, and hidesall rough and unfinished edges.

A most noticeable improvement in this device lies in the fact that it isunnecessary to drill holes in the slates to secure them in place.

Inv the modification shown" in Fig. 5, the sides and flanges I) are thesame, and the lugs n iy be punched 1" rom these sides inward ly at rightangles thereto, or they may be punched from the central section of thepart in which case they would be bent in at a lesser angle. the objectbeing to punch the lugs from the piece B into a plane substant allyparallel with the outer sides or flanges, tnerehy forming a spacebetween the sides and. the lugs for the slate. The lining piece C, whichmay be straight or curved, will fit around the lugs in a similar manneras before statedv I claimas my invention 1. A corner piece for panelboards and the like, comprising an angular metallic piece with llau ededges, lugs punched from said piece into planes substantially parallelto flanged edges, in combination with s to secure the boards betweensaid lugs d flanged edges, substantially as described. 12. ii. cornerpiece for panel'boards and the like, comprising an angular metallicpiece LG flanged edges, lugs punched. alternately from the sides of saidpiece into planes substantially parallel said flanged edges, incombination with means to secure the boards TIO edges set at an angle toreceive" securing screws, substantially as described.

4. A corner piece for panel boards and the like, comprising an angularmetallic piece with flanged edges, lugs punched from said piece intoplanes substantially parallel to said flangededges, a plate at one endof said piece for securing the same to the base of said panel board, incombination with means to secure the boards between said lugs andflanged edges, substantially as described.

A corner piece for panel boards and the like, comprising an angularpiece with flanged edges, and lugs unched from said piece into a planeparalle with the flanged edges, in combination with a. corner liningpiece, having inwardly bent flanges adapted to cover said lugs.

6. A corner piece for panel boards and the like, comprising an angularpiece with flanged edges, lugs punched from said piece into planessubstantially parallel 7 said edges. in eon'ibination with a cornerlining piece. having inwardly bent flanges adapted to ill between saidlugs and the sides of said panel board.

7. A corner piece for panel boards and the like, comprising anvangularpieee with flanged edges, and lugs punched iri'nn said piece intoplanes parallel with the flanged edges, in combination with a cornerlining piece and means for securing the same in place, sub- .ai'itiallyas described.

8. A corner piece for panel boards and the like, comprising an angularpiece with flanged edges, lugs punched from said piece into planessubstantially parallel to said flanged edges, in combination with acorner lining piece having a plate. at one end thereof and means forsecuring said lining )icce between the lugs and panel board,substantially as described.

In testimony whereof I have signed my name to this specii'ication, inthe presence oi two subscribing witnesses.
